Abstract
This invention relates to a method for drying the charge of a unit that treats petroleum cuts with a low water charge that consists in injecting a hydrolysable chemical compound into said charge. The quantity of the chemical compound injected is at least equal to the quantity necessary for all the water contained in the charge to react by hydrolysis with said chemical compound. The invention finds its application in units that treat petroleum cuts and whose operation is sensitive to the presence of water in their charges, in particular the paraffin base hydrocarbon isomerisation units.
